CLIMATE-READY VICTORIA HUME How climate change will affect the Goulburn Broken and North East and how you can be climate-ready The Hume region has already become HUME HAS BEEN GETTING WARMER AND DRIER. IN THE warmer and drier – a climate trend FUTURE THE REGION CAN EXPECT: likely to continue into the future. Local residents, businesses and temperatures to continue more hot days and to increase year round warm spells communities are changing the way they do things in response. Getting less rainfall in autumn, winter fewer frosts climate-ready involves understanding and spring how climate change is likely to affect more frequent and more harsher fire weather and you and your region, and working intense downpours longer fire seasons out ways to adapt. Everyone can contribute to the Hume region’s climate-ready future. HOW WILL THESE CHANGES AFFECT YOU, AND WHAT CAN YOU DO ABOUT THEM? This publication highlights the impacts climate change will have on the Hume region. It gives examples of how people are already becoming climate-ready, with links to more detailed information. While this publication is about adapting to climate change, reducing your carbon emissions by reducing energy use and switching to renewable energy sources is also important in getting climate-ready.

Human activity is causing climate change, through our temperatures currently range from 20°C in the alpine areas, to release of greenhouse gases from the burning of fossil fuels, 31°C on the lower slopes and plains. Winter average maximum land use change and agriculture. Atmospheric concentrations of temperatures range from 4°C in the alpine areas to 12°C on carbon dioxide are now more than 40% higher than they were the plains. Frosts can occur over the entire region between before industrialisation. April and October. There is occasionally snow in the mountains above 1000 m. In the Hume region, the rate of warming has increased since 1960. Rainfall currently ranges from 2000 mm in the alpine areas to less than 500 mm on the plains. Most rainfall occurs in winter On average, rainfall has declined since the 1960s, especially in and spring. Summer thunderstorms are common, contributing autumn. The harsh Millennium Drought (1996 to 2009) ended to the risk of fires and floods. with two of the wettest years on record in 2010–11.

Temperature change in the Hume region since 1950 1.4-1.6oC CLIMATE VARIABILITY AND CHANGE 1.2-1.4oC Our climate varies – it always has and always will. This 1.0-1.2oC climate variability means that some periods are cooler and Rainfall change wetter than average (as was the case in the 1970s), while in the Hume region since 1950 others are hotter and drier (such as during the Millennium Drought). However, due to climate change, the long-term average is changing.

CLIMATE-READY NOW Getting climate-ready is an ongoing process, and there’s no Victorians have always been good at managing the ups and single recipe for success. Many of the risks we face are not downs of climate. Now that we have a clearer picture of the new. However, there are likely to be changes in duration, way in which climate is likely to change in future, there’s lots frequency and severity of some weather events, as well as that we can do to become climate-ready. Decisions we make changes to the climate. now will affect how well we cope with the changing climate, To determine what’s important to you and what climate change which in turn will affect future economic and employment responses might work for your situation, consider these conditions. Decisions range from simple to complex, and questions: some will need to be made sooner than others. Your decisions may depend on the local climate in your part of the region. c How might you – your health, property, business, community, industry – be affected by: There are many good examples of communities in your region and in Victoria preparing for and adapting to • higher temperatures and more frequent heatwaves? climate change.

Through the Birchip Cropping Group, researchers worked with farmers to assess how different climate change scenarios are likely to affect cereal crop yields. The costs and benefits of different adaptation options were examined, including changed crop varieties and planting schedules, to see the extent to which farmers could offset the adverse impacts of climate change. Dairy Australia’s Dairy Climate Toolkit provides comprehensive details of the practices that profitably reduce greenhouse gas emissions from dairy farm systems, and adaptation strategies such as addressing heat stress and responding to changes in pasture.
